ABSTRACT:
An internal combustion engine has an air-fuel mixture compressed through operation of a turbocharger whose turbine is driven by the exhaust gas from the engine and whose compressor is driven by the turbine. The pressure within the intake manifold is used to produce a signal by means of which the winding of a solenoid-operated direction valve is energized. A flapper valve located within the exhaust gas manifold opens and closes passages within the turbine casing through operation of the solenoid valve. A piston actuates the flapper valve in accordance with intake manifold pressure. Exhaust gas is directed either entirely at high speed through a first passage or at low speed through a second passage, the cross sectional area of the first passage being substantially less than that of the second passage.
